Description
Technical field
The present invention relates to a kind of combined types for large-scale semi-submerged ship to help floating device and its construction method, belongs to large ship
With offshore engineering technical field.
Background technique
The self weight of ship and Offshore Platform Construction is gradually increased, if gross weight reaches 10W tons of lifting pipe laying vessel partly latent, hull
Volume is huger, up to 200 meters, it is wide up to 60 meters, the construction of these ships uses the sectional construction in workshop substantially, in dock
It inside carries out segmentation and block closes up, close up after finishing and filled the water into dock, enter after so that drauht is met certain requirements
Predetermined navigation channel carries out fitting-out and the test of next step.By dock size itself and the limitation of construction ability is allowed to be influenced,
It is frequently encountered in the construction of ship platform and sail during since shipping draft is greater than the depth of water of navigation channel or dock,
It can not sail so as to cause ship grounding or hull bottom and the bottom less than safe distance or reach designated place by shallow waters,
The progress sailed He be further delivered for use for not only affecting ship platform, also results in the damage of hull bottom and dock bottom, makes
At huge economic loss.Solving this problem, there are two types of thinkings, first is that increasing a certain amount of buoyancy for hull to guarantee safety
It undocks, second is that by waters installation of some unstructuredness facilities outside dock to mitigate self weight.Current major shipyard is common
There are two types of methods, first is that floating, this monoblock type buoyancy tank is helped using one-piece steel buoyancy tank, it is bulky, it builds, transport, storage
Difficulty, the scope of application is small, and detailed design is needed before production.Another method is only to install a part of equipment in dock to mitigate certainly
Weight, this method will lead to extension construction period, and at sea installation equipment implements more complicated, and economy is poor.
Summary of the invention
The present invention, which provides, regarding to the issue above a kind of large-scale combined helps floating device and its construction for what is used in dock
Method, this combined type help floating device to be formed by multiple buoyancy tank body combinations, and the surrounding of this buoyancy tank main body can be floating with other
Box main body connection can be assembled into suitable for helping floating device under a variety of different situations, connect, install with hull part again later
Process is located in dock.After ship undocks, the connection for helping floating device and hull is released, it is floated on the surface of the water, thus recycled,
The connection between buoyancy tank main body and buoyancy tank main body is released again, is transported and is stored.
The technical solution adopted by the present invention to solve the technical problems is: a kind of combined type for large-scale semi-submerged ship helps floating
Device, described to help floating device include buoyancy tank main body, and described to help floating device further include connecting plate, means of communication, buoyancy regulating and controlling mechanism
